Thanks for your interest in contributing! This project aims to maintain a high-quality, opinionated collection of performance engineering tools and resources.
- New tools that fit the performance engineering scope (observability, performance testing, profiling, chaos engineering, etc.)
- Improvements to existing descriptions or categorization
- Corrections to broken or outdated links
- New categories backed by concrete use cases
- Learning resources (books, articles, talks) of lasting value
- Unmaintained or abandoned tools (no activity for 2+ years without explanation)
- Tools without documentation or public references
- Duplicate entries across sections (use cross-references instead)
- Purely promotional or marketing-driven content
- Tools that require private access or have no public information
The easiest way to contribute is to open an issue using the Tool Suggestion template. This lets us discuss the tool before adding it.
- Fork the repository
- Create a branch from
main(git checkout -b add-tool-name) - Add your entry following the format conventions below
- Submit a pull request with a clear description of why this tool belongs here
Each tool entry follows this pattern:
* **[Tool Name](https://tool-website.com/)** INDICATORS — One to three sentence description. What it does, what makes it notable, where it fits. [Language] [License] — [GitHub](https://github.com/org/repo)Indicators are emoji tags from the legend in each list (e.g., ⭐🟢🔵📚). Apply them honestly based on the tool's actual status, not aspirations.
Guidelines for descriptions:
- Be factual and concise (1-3 sentences)
- Mention what makes the tool distinctive, not just what it does
- Include the primary language, license, and GitHub link when available
- For commercial tools, use
[Commercial]instead of a license
- Add new tools at the end of the relevant section (we reorder periodically)
- If a tool spans multiple categories, place it in the most relevant one and add cross-references
- Every link must be valid and point to an official or canonical source
- Descriptions must be original (not copied from the tool's own marketing)
- Indicators must be accurate and applied consistently with existing entries
- Commercial tools are welcome but must be clearly marked with
🟠
